Can Lyrica (pregabalin) cause heart rhythm problems?
Lyrica (pregabalin) can affect the nervous system and, in rare cases, has been associated with heart-related side effects. However, the provided information does not include specific evidence or details about a direct link between Lyrica and cardiac arrhythmias (like atrial fibrillation, ventricular tachycardia, or QT prolongation), so the exact risk and mechanism can’t be confirmed here.
If someone taking Lyrica develops symptoms such as fainting, severe dizziness, a rapid or irregular heartbeat, or chest pain, they should seek urgent medical care.
What symptoms might suggest an arrhythmia while taking Lyrica?
People commonly associate arrhythmia symptoms with:
- palpitations (feeling the heart is racing or fluttering)
- dizziness or lightheadedness
- shortness of breath
- fainting (syncope)
- chest discomfort
These symptoms can also occur for non-arrhythmia reasons, but they still warrant prompt medical evaluation, especially if they start after beginning or changing the dose of Lyrica.
Who might be more at risk?
Risk depends on more than the drug alone. Clinicians typically consider factors that increase susceptibility to rhythm problems, such as:
- history of arrhythmia or structural heart disease
- electrolyte abnormalities (low potassium or magnesium)
- other medicines that affect heart rhythm or blood pressure
- dehydration or kidney problems (which can change drug exposure)
The key point for patient safety is that combining Lyrica with other interacting risk factors can matter, even if Lyrica alone is not the only cause.
Can other medicines taken with Lyrica increase arrhythmia risk?
Arrhythmia risk can rise with drug combinations that affect heart rate, blood pressure, or electrical conduction, or if they alter electrolyte balance. The provided information doesn’t list specific interacting drugs with Lyrica here, so you’ll need to check your medication list with a pharmacist or prescribing clinician.
If you share:
- your age,
- your Lyrica dose (and when you started or increased it),
- your arrhythmia type (if known),
- and the other medications you take,
I can help you think through what to ask your clinician.
What should you do if you suspect Lyrica is triggering palpitations or arrhythmia?
- Do not stop Lyrica abruptly without medical advice; stopping suddenly can cause withdrawal or rebound symptoms.
- Contact the prescriber quickly to report new or worsening palpitations, dizziness, or fainting.
- If symptoms are severe (fainting, chest pain, or sustained rapid/irregular heartbeat), go to urgent care or the emergency department.
Are there alternatives to Lyrica if heart rhythm is a concern?
If you’re concerned about heart rhythm side effects, clinicians may consider dose changes or alternative treatments for the condition Lyrica is being used for (for example, neuropathic pain or fibromyalgia). The right substitute depends on the diagnosis, medical history, and current medications.

What I need to answer more precisely
Right now, “Lyrica and heart arrhythmia” is too broad to confirm the specific claim (risk magnitude, which arrhythmias, and whether it’s an established adverse effect). If you answer any of these, I can tailor the guidance:
1) What condition is Lyrica treating (neuropathy, fibromyalgia, seizures, other)?
2) Your dose and how recently you started or increased it?
3) What arrhythmia was diagnosed (or what symptoms are you seeing)?
4) Any other heart medicines or medicines that affect electrolytes (diuretics, beta blockers, antiarrhythmics, antidepressants, etc.)?
5) Kidney function issues, since pregabalin dosing depends on renal clearance.
